Split up days

Ruby
1

hi

problem is …

I got date @start and date @stop as a date and I can display like

@start = Thu Jan 19 00:00:00 CST 2006
@stop = Tue Jan 21 00:00:00 CST 2006

how to split up this days and put to array ?

array[] = “Thu Jan 19 00:00:00 CST 2006
Wed Jan 20 00:00:00 CST 2006
Tue Jan 21 00:00:00 CST 2006”

is there some function which can do that ?

thanks for help

robert

thank you for answer .
from FORM I can select days, FROM - TO
like from Monday to Friday
exanmple:

from 2006-01-20 to 2006-01-24

and than I need to put each day to database as five days like

2006-01-20
2006-01-21
2006-01-22
2006-01-23
2006-01-24

so first I need to put each day to array and that in loop put each day
to database.

this is what I want
thanks for help

def toSecond(stime)
atime=stime.split("-")
return Time.local(atime[0],atime[1],atime[2]).to_i
end

@start = “2006-01-20”
@stop = “2006-01-24”

array=Array.new
toSecond(@start).step(toSecond(@stop),86400) do |t|
array.push(Time.at(t).strftime("%Y-%m-%d"))
end

puts array

Is this ok?

This is not valid Ruby code. What types are these objects?

You assign a string but you seem to want an array. Also, you don’t seem
to want to split but to append.

split at whitespace

array = @start.to_s.split /\s+/

split into array, works for Time

array = @start.to_a

put into array

array = [@start, @stop]

concatenate

array = “#{@start}\n#{@stop}”

is there some function which can do that ?

If you tells us what you actually want, we might be able to come up with
an answer.

Cheers

Now we’re cooking. How’s that?

require ‘date’

fetch start and end date from somewhere

start=Date.today
endd=start+30
d=start
while d < endd
puts d
d += 5
end

this is super but why when I will put 2006,3,2 into variable
like @start = “2006,1,3” and @stop = “2006,1,4” does not work ?
days = (Date.new(@start)…Date.new(@stop)).to_a

undefined method `-’ for “2006,1,3”:String

It’s easy to transfer the string “year, month, day” to the parameter
format that meets the requirement of Date.new(year, month, day) :

date_start = @start.split(’,’).map {|x|, x.to_i}
date_stop = @stop.split(’,’).map {|x|, x.to_i}
days = (Date.new(@start)…Date.new(@stop)).to_a

Still elegant?

Range can help you. Example:

require ‘date’
days = (Date.new(2006,1,20)…Date.new(2006,1,24)).to_a
days.each {|date| puts date}
=>2006-01-20
=>2006-01-21
=>2006-01-22
=>2006-01-23
=>2006-01-24

oops, the last line should be:

days = (Date.new(date_start)…Date.new(date_stop)).to_a

I got like

@start = @params[‘start’][‘year’].to_s + “,” +
@params[‘start’][‘month’].to_s + “,” + @params[‘start’][‘day’].to_s

@stop = @params[‘stop’][‘year’].to_s + “,” +
@params[‘stop’][‘month’].to_s + “,” + @params[‘stop’][‘day’].to_s

and I try to put to
days = (Date.new(@start)…Date.new(@stop)).to_a

still got this error undefined method `-’ for “2006,1,3”:String

BTW what is “x” => date_start = @start.split(’,’).map {|x|, x.to_i} ?
^ ^

or is going about (’,’) ? hmm

because is error
…/script/…/config/…/app/controllers/hour_controller.rb:178: parse
error, unexpected ‘,’
date_start = @start.split(’,’).map {|x|, x.to_i}
^

11

I removed , from date_start = @start.split(’,’).map {|x| x.to_i}
^

now got
private method `split’ called for Tue Jan 24 00:00:00 CST 2006:Time

12

ups to put to

date_start = @start.split(’,’).map {|x|, x.to_i}

I try format like this

@start =
Time.local(@params[‘start’][‘year’],@params[‘start’][‘month’],@params[‘start’][‘day’])

the same error :frowning:

sry, I copied a wrong part of my own code. What I tried to do is to
split the string “year, month, day” into 3 integers and store in an
array [year, month, day], then create Date objects from the arrays.

def new_date(date)
Date.new(date[0], date[1], date[2])
end

date_start = @start.split(’,’).map {|x|, x.to_i}
date_stop = @stop.split(’,’).map {|x|, x.to_i}
days = (new_date(date_start)…new_date(date_stop)).to_a

This should work now.
